A new chimney liner, patching, and waterproofing on a chimney in Abington, Massachusetts.
This project in Abington, MA brought together two jobs that protect a chimney from different directions. The chimney liner installation carries exhaust out of the home and shields the masonry from combustion gases. The patching and waterproofing on the chimney help keep rain and snowmelt out of the structure.
Water and exhaust both wear on a chimney over time, which is why they are often addressed together. Moisture that gets into masonry can freeze, expand, and widen cracks. Our waterproofing solutions are meant to be applied once the masonry is sound, so any damage is repaired first.
The work on this Abington chimney had three parts. We installed a new flexible metal chimney liner. We patched the chimney above the roofline and finished the stack with a textured coating, smoothed by hand. We then waterproofed the masonry to help keep moisture out.
The Abington chimney now has a new liner, a patched and coated stack, and a stainless steel cap with perforated sides over the flue, with metal flashing at the base. The purpose of this work is to give the flue a dedicated path for exhaust and to help protect the masonry from water.

It gives exhaust a continuous path out of the home and protects the masonry from heat, combustion gases, and condensation. A cracked or missing liner can shorten the life of the masonry and let smoke or gases escape where they should not.
Patching repairs damaged areas, and waterproofing helps keep water from getting back in. Waterproofing works best on a sound chimney, which is why repairs come first.

Not when a breathable sealant is used. It blocks liquid water from the outside while letting vapor already in the brick escape. That is also why we repair damage first, since sealing over a crack would lock the problem in.
It is worth having the liner inspected. Modern high-efficiency gas appliances produce more acidic condensate, which can damage an older chimney quickly, and a cracked clay liner can let smoke and carbon monoxide reach living spaces or attic cavities. An inspection will show whether the existing liner can stay or should be replaced.
